Audio A retired from the stage and recording studio in 2007 after serious medical issues silenced Stuart’s singing voice.

“I developed a voice disorder from screaming at concerts for 20 years,” he told the audience in a raspy voice that didn’t sound much better than it did at the group’s last Lexington concert, a few blocks over from Broadway Christian in Rupp Arena in the Spring of 2007. “But the thing is, in losing my voice, I have become the voice for thousands of orphans in Haiti.”

And that’s what brought Stuart and Audio Adrenaline bassist Will McGinniss to Lexington Saturday along with worship artists the Know Hope Collective. The group led the audience at Broadway Christian in worship and talked extensively about the Hands and Feet Project, Audio A’s charity that operates orphanages in Haiti and the Know Hope Foundation, which operates in Haiti and the Ukraine.

They told the stories of several orphans, including Stuart’s adoptive daughter, Christela, who they said was born in Haiti to a 14-year-old girl in an outhouse, dropped into the toilet and left to die. Very soon after that, she was rescued by United Nations Peace Keeping troops. Stuart said that after the dramatic rescue, which they showed video of, the soldier who was lowered into the pit to retrieve Christela asked to name her.

Christela, Stuart said, means “Christ was here” in Creole.

“When you reach out to help the abandoned, you understand what it is for God to reach out to us,” Stuart told the crowd.

The event opened with the story of Mackenson, a boy born during the Haitian earthquake in January 2010 who was given up to the Hands and Feet orphanage by his mother who did not want to care for him after it was discovered he was HIV positive. Today, a video about the boy said, he no longer has HIV.

The orphanage and charity were named after one of Audio Adrenaline’s signature songs, Hands and Feet, one of only two Audio A songs that were performed Saturday night. The other was their hit Big House, Stuart’s one real turn at singing as he barked the verses and pantomimed throwing a football across the stage to McGinnis on the line, “A big, big yard, where we can play football.”

No, raising rock ‘n’ roll memories was not the point of the Saturday night’s event. But it was a few moments of fun in the midst of what has become a very serious endeavor for the Audio Adrenaline veterans.
